ENGLISH

Congratulations upon your selection of this CASIO watch.

Note that the product illustrations in this manual are intended for reference only, and so the actual product may appear somewhat different than depicted by an illustration.

This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

Warning!

The measurement functions built into this watch are not intended for taking measurements that require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before using it. The watch may produce incorrect direction readings if you do not perform bidirectional calibration. For more information, see “To perform bidirectional calibration” (page E-37).

Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you or any third party arising through the use of this product or its malfunction.

Loosen

The crown of this watch is a screw in lock crown. Before using the crown, you must first rotate it towards you to loosen it.

Important!

To maintain water resistance and avoid impact damage to the crown, be sure to screw it back in when you are not using it.

The illustrations below show the different crown operations.

Pull out

Rotate

Push in

High-speed Movement

When rotating the crown to move the hands of the watch, you can use the operations described below to move the hands at high speed, either forward or back. There are two high-speed levels: HS1 and HS2 (faster than HS1).

E-2	E-3

To start HS1 high-speed movement

While the crown is pulled out, rotate it rapidly three turns away from you (for

forward movement) or towards you (for reverse movement). High-speed movement will continue even if you release the crown.

To start HS2 high-speed movement

While HS1 high-speed movement is progress, again rotate the crown rapidly three

turns in the same direction as the current HS1 movement (away from you for forward movement or towards you for reverse movement).

To stop high-speed movement

Rotate the crown in the direction that is opposite that of the current high-speed movement or press any button.

Note

If you do not perform any operation for more than two minutes after pulling out the crown, crown operations will become disabled automatically. If this happens, push the crown back in and then pull it out again to re-enable crown operations.

You can use high-speed hand movement when confi guring time settings in the Timekeeping Mode, Alarm Mode, or Countdown Timer Mode.

Button operations become disabled after you perform a crown operation. If this happens, rotate the crown slightly. This should restore button operations.

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Important!

Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.

Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

Whenever you are not wearing		When wearing the watch, makes

Warning!

Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

On the dashboard of a car parked in direct sunlight

Too close to an incandescent lamp

Under direct sunlight

Checking the Current Power Level

You can use the procedure below to determine the watch’s current power level. Certain functions will be disabled when the power level is low. If the power level is low, leave the watch in a location where its face (solar panel) is exposed to light.

To check the current power level

1.In the Timekeeping Mode, press B. The x Second Hand will move to H (High), M (Mid), or L (Low) to indicate the power level.

H: High
M: Mid
L: Low

E-10	E-11

2.If about two seconds elapse without any operation being performed, the x Second Hand will then move to the latest time calibration signal receive operation result.

See “To check the result of the latest receive operation” (page E-20).

3.Press Bto return to regular timekeeping.

The watch will also return to regular timekeeping if you do not perform any operation for about 10 seconds.

Low Power

Moves at two-second intervals.

Low power conditions are indicated by the movement of the x Second Hand in the Timekeeping Mode.

If the x Second Hand is moving normally at one-second intervals, power is at Level 1.

If the x Second Hand is moving at two-second intervals, power is at Level 2, which is quite low. Expose the watch to light as soon as possible so it can charge.

	3	x Second Hand stopped.	All functions disabled

When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

When the watch is at Level 3, exposing it to light for a while will cause the x Second Hand to move to the position of second 57. This indicates that charging has started.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to continuous signal reception or other operations over a short period. Note that all operations are disabled while the watch is in the power recovery mode.

The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain there.

The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

To recover from the sleep state

Move the watch to a well-lit area or press any button.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Configuring Current Time and Day Settings Manually” (page E-28) for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

	If your Home City Code setting is this:	The watch can receive the signal from the
		transmitter located here:
	LON (LONDON), PAR (PARIS), ATH (ATHENS)	Anthorn (England), Mainflingen (Germany)

3.What you should do next depends on whether you are using Auto Receive or Manual Receive.

Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” on page E-18 for details.

Manual Receive: Perform the operation under “To perform manual receive” on page E-19.

Auto Receive

With Auto Receive, the watch performs the receive operation each day automatically up to six times (up to fi ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according

to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.

When a calibration time is reached, the watch will perform the receive operation only if it is in the Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you are confi guring settings.

To perform manual receive

1.In the Timekeeping Mode (page E-24), keep Bdepressed (for about two seconds) as the xSecond Hand goes through the following sequence.

Moves to H (High), M (Mid), or L (Low) to indicate the power level and then moves to R (READY).

2.The x Second Hand indicates the operations the watch is currently performing.

When the x Second Hand is pointed here: It means this:

R (READY)

Watch is setting up for reception.

W (WORK)

Reception is in progress.

If signal reception is unstable, the x Second Hand may move between

W (WORK) and R (READY).

When the receive operation is successful, the watch adjusts the time

setting accordingly, and then resumes regular timekeeping. It does not

adjust the setting if the operation failed.

Signal reception is not performed when the power level is L (Low).

Note

To interrupt a receive operation and return to the Timekeeping Mode, press any button.

E-18	E-19

To check the result of the latest receive operation

In the Timekeeping Mode, press B. The x Second Hand will move to H (High), M (Mid), or L (Low) to indicate the power level, and then it will

indicate the latest time calibration signal receive operation result.

The x Second Hand will move to YES (Y) if the latest receive operation

was successful, or NO (N) if it was not. After about 10 seconds, regular

timekeeping will resume.

Press Bto return to regular timekeeping. The watch will also return

to regular timekeeping if you do not perform any operation for about

10 seconds.

Note

The x Second Hand will indicate NO (N) if you have adjusted the time or day setting manually since the latest receive operation.

To turn auto receive on and off

YES (Y) 1. In the Timekeeping Mode, press B. The x Second Hand will move to H (High), M (Mid), or L (Low) to indicate the power level, and then it will indicate the latest time calibration signal receive operation result.

2. Pull out the crown.

The x Second Hand will perform one full revolution and then stop at the

current on/off setting.

3. Rotate the crown to move the x Second Hand to the setting you want.

To turn on auto receive, select YES (Y).To turn off auto receive, select NO (N).

4. Push the crown back in to return to the Timekeeping Mode.

Radio-controlled Atomic Timekeeping Precautions

Strong electrostatic charge can result in the wrong time setting.

Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.

The watch is designed to update its day setting automatically for the period from January 1, 2000 to December 31, 2099. Updating of the day setting by signal reception will no longer be performed starting from January 1, 2100.

If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications” (page E-64).

The receive operation is disabled under any of the following conditions.

−While power is at Level 2 or lower (page E-12)

−While the watch is in the power recovery mode (page E-13)

−While the watch is in the function sleep state (power saving, page E-14)

−While the watch is not in the Timekeeping Mode

−While a direction reading or Countdown Timer operation is in progress (even if the watch is in the Timekeeping Mode)

A receive operation is cancelled if an alarm sounds while it is being performed.
